headings, alt image attributes, backlinks and internal links anchor text. Keyword density of above 6% can indicate that the word or a phrase appears too
many time in the content.

Custom 404 Error Page
No custom 404 error page detected.
A 404 is a standard http response code for a resource that cannot be located on the server. Web servers usually return a "404 Not Found" error page for non-existing pages. Unfortunately, these default error pages are very generic and a not very user friendly, therefore, using a custom 404 error page is highly recommended.
Process of returning http status code "200 OK" for a non-existent page or redirecting users to another url is called soft 404. Soft 404 errors are problematic for search engines and are not advisable. (https://support.google.com/webmasters/answer/181708)
